‘Transformer’ pulsar is more than meets the eye

These artist's renderings show one model of pulsar J1023 before (top) and after (bottom) its radio beacon (green) vanished. Normally, the pulsar's wind staves off the companion's gas stream. When the stream surges, an accretion disk forms and gamma-ray particle jets (magenta) obscure the radio beam.

Massive neutrinos and new standard cosmological model: No concordance yet

Update: Einstein is still full of surprises

What is the view of time that Albert Einstein presents to us in special relativity? Einstein tells us that there is no separate ‘time’ or ‘space.’ ‘Time’ and ‘space’ cannot be separated; they are a united whole.

Let me ask you this: ‘Are bananas radioactive and is it true that eating too many can kill you?’

Yes, you will certainly die from radiation poisoning if you are able to eat 10,000,000 bananas at once. You may also witness chronic symptoms if you eat 274 bananas a day for seven years. — Yes, you will certainly die from radiation poisoning if you are able to eat 10,000,000 bananas at once.

Small, but plentiful: How the faintest galaxies illuminated the early universe

A view of the entire simulation volume showing the large scale structure of the gas, which is distributed in filaments and clumps. The red regions are heated by UV light coming from the galaxies, highlighted in white. These galaxies are over 1000 times less massive than the Milky Way and contributed nearly one-third of the UV light during re-ionisation. The field of view of this image is 400,000 light years across, when the universe was only 700 million years old. (Credit: John Wise)

Venus can be seen as a black dot eclipsing the Sun in this image from 2012. Venus orbits too close to the Sun to the planet to be habitable for life as we know it.
